B001: AND BINDING;

* and Bindings, of which the following is a specification.

' Our invention relates to the class of books in which the signatures, adapted to hold musical records, trade samples, or the like, are detachably secured to the back, the object being the production of a simple, comparatively cheap, and practically, indestructible book of the character designated adapted to the exacting requirements of common use. I a I The invention consists in the construction and arrangement of parts described and claimed specifically, distinctive features being the formation of the rigid sheet metal back spine, the means provided for the attachment of the side covers thereto, and the formationof the signatures, all as hereinafter more fully set forth. a

I In the accompanying drawings, Figure l,

Specification of Letters Patent.

Application filed June 30, 1915. Serial No. 37,227.

patented Dec. 7, 1915.

The face plate 8*, issecured to the-back plate 8, by means of inturned flanges on the latter,--t'. 6., the longitudinal side flanges s, s, and the end flanges s s ,the latter forming part of the upset ends s 8 of the back plate s, as shown more particularly in Fig. 7. In other words the face plate 8*, of plain elongate rectangular shape, abuts at its ends against the straight upturned portions s .9 of the back plate 8, and at its longitudinal edges against the concave surface of the saidback plate 8, the inturned flanges s, s, ands 8 holding and securing it in position against saidconcave surface of the back plate. Before the face plate .9", is thus attached to the back plate 8, however, the binding cloth'or hinge cloth in, used for the articulatory attachment of the side covers 0, c, is inserted between them so that the inturningof the longitudinal side.

flanges s, s, of the back plate 8, will clamp said hinge cloth k, between it and the longitudinal edges of the face plate 5, as shown more particularly in Figs. 4, and 5,the longitudinal marginal edges of said binding cloth it, protruding sulhciently to afford ample surface for attachment to the side boards or covers 0, c, in the manner well known in the art of book binding,-0, representing the usual exterior covering of the back spine connected with said side ,covers 0, c, and the edges of the hinge cloth it, being overlapped and concealed in the finished article by the customary inner side cover linings 0 c I The inturned end flanges 3 of the spine S, are formed with perforations 0r recesses s st, for the reception of the ends of the signature rods 1", 7, which are preferably made of elastic resilient metallic wire of appropriate length to admit of the springing of the ends into said holes orseats 3*, .9

One or more intermediate signature rod guards or retainers r, 7", are provided upon the face plate 8, as may be found most expedient, according to the size and purpose of the book. Two of these auxiliary or reinforcing retainers r, r, are shown in the ner, we prefer to form them with spurs or tongues r r which fit in and through transverse slots s 8 formed for their reception in the spine face plate s ,--the ends of said tongues being bent up against the rear side of said face plate 8X, to clench the holder plates 1", r, rigidly in position so that they constitute practically an integral part of the face plate s ,-being attached thereto as a preliminary step in the construction of the spine.

The leaves of the signatures used in connection with our back spine and connections, are united by articular ligaments a, the longitudinal edges of which are each interposed between the edges of two superposed sheets or thicknesses e, c, of paper or other material combined to form either an envelop, as when used for music records, or twin sheets for the display of samples, or the like according to the nature and object to which the book is adapted. The said longitudinal edges of the ligament a, are pasted or otherwise adhesively attached to the opposed inner sides of the leaf sheets 6, c, after which a binding tape 6, is adhesively attached to the overlapping edges, being passed around both sides of the leaf, and then further and positively secured in position by a line of stitching b, as indicated particularly in Figs. 2, 3, and 8. Te thus attain a signa ture of exceptional strength and durability, and one especially adapted to our construction of back, since the single thickness of articular ligament a, made of suitable flexible and tenacious material, affords a simple but effective means of contacting with the signature rod 9", inserted in the bight of the folded signature, as illustrated in Fig. 8,-it being understood that the ligament a, is formed with central transverse slits a, (see Fig. 3,) coincident with the position of the intermediate signature rod plates 1", the upper edges 1, of which are curved concentric to the holes 1, so as to protrude through said slits a. In securing a signature in position upon the back, the signature is simply laid flat on the extended cover with coinciding parts of the rod plates1"',protruding through the slits a, in the ligament a, and a rod 7", is

then passed through the exposed holes 1"", and into a coincident seat 8 in one end flange s ,the other end of the rod being sprung into the corresponding seat 8 in the other end flange s ,-thus locking the signature in position against either lateral or longitudinal creep, looseness, or displacement. In this connection it will be seen that the perforated protuberances r", in conjunction with the slits a, in the signature web or ligament or, perform an important function in our construction and arrangement of parts.

Provision is made for the accommodation of as many signatures as the character of the book renders expedient; and a signature may be readily removed and another substituted in its place without disturbing the others in place within the cover. Furthermore thestructure as a whole, while simpler and comparatively inexpensive, is strong and substantial, and not liable to get out of order under ordinary conditions of use.

What we claim as our invention and desire to secure by Letters Patent is,

1. In a book of the character designated, a spine comprising a -flat elongated face plate and a concavo convex back plate formed with inturned longitudinal edges and inturned end flanges binding said face plate to the back plate, the said inturned flanges of the back plate being formed with recesses for the ends of signature rods, and the said face plate with transverse retaining guides for said signature rods, together with said signature rods, and signatures held in position thereby.

2. In a book of the character designated, the combination of a spine comprising a flat elongated face plate and a concavo convex back plate formed with inturned longitudinal edges and inturned end flanges binding said face plate to the back plate, a side cover binding medium interposed between said face plate and back plate and clamped in position by the inturned longitudinal flanges on the back plate, side covers attached to said binding medium, and signatures articulately connected with said spine.

3. In a book of the character designated, the combination with the spine adapted to receive and retain signature rods of a signature comprising a flexible ligament the edges of which are interposed between and attached to sheets forming the leaves of the signature, for the purpose described.

t. In a book of the character designated, the combination with the spine adapted to receive and retain signature rods, of a signature comprising a flexible ligament the edges of which are interposed between and attached to sheets forming the leaves of the signature, the connection between said leaves and said ligament being further secured on both sides by a binding tape adhesively secured to both leaves and ligament.

5. In a book of the character designated, the combination with the spine adapted to receive and retain signature rods, of a sig nature comprising a flexible ligament the edges of which are interposed between and attached to sheets forming the leaves of the signature, the'connection between said leaves and said ligament being further secured on both sides by a binding tape adhesively secured to both leaves and ligament, and the ligament, leaves and binding being further and positively secured together by stitching.

6. In a book of the character designated, a spine comprising a flat elongate face plate and a concavo-convex back plate, the face lZO plate being, held in position upon said back ]plate by inturned longitudinal flanges and V inturned end flanges, the latter flanges being formed With recesses for seating the ends of signature rods, said signature rods, andmedial guide plates for said signature rods positioned on the face plate and secured thereto by tongues passing therethrough and clenched on the back side thereof, said medial guide plates beingalso formed With protuberances concentric with the signature rod holes formed therein, and signatures having medial ligaments slitted to receive said protuberances.

7. In a book of the character designated,

a spine comprising a flat elongated face plate and a concavo convex back plate formed with inturned longitudinal edges and inturned end flanges binding said'face plate to the back plate, the said inturned flanges of the back plate being formed With recesses for the ends of signature rods, together With said signature rods and signatures held in position thereby.
